Defining Information technology security is a broad measure of protection for computer networks and their data. It protects organizations against breaches, leaks, publication of private information, or attacks. There were half a million cyber crimes committed in the United States in 2022 that totaled more than $10 billion in losses.
In 2022 the most costly cyber crime category was investment fraud which resulted in $3.31 billion in losses. According to Express VPN, cyber attacks rose to $8 trillion worldwide in 2023 and are expected to rise to $10.5 worldwide by 2024. IT security specialists play a significant role in keeping these figures from rising even higher. Contact ITI Technical College today for more information.
What Is The Role Of Information Technology Security?
Information technology security seeks to protect organizations’ computer systems, networks, and software from unauthorized access and attacks from:
- Hackers
- Malware
- Spyware
- Ransomware
- Viruses
- Worms
IT security systems put processes in place to (1) identify and block unauthorized access attempts, (2) protect the integrity and privacy of data, (3) identify and block malware, and (4) prevent data theft and misuse. IT professionals implement security measures, monitor for incidents, and respond to security breaches.
Defining Information Technology Security involves implementing comprehensive strategies that utilize advanced technologies and human expertise to counter cyber threats effectively. These strategies encompass protective measures for hardware systems, software applications, and endpoints to safeguard against unauthorized access, data breaches, and malicious attacks. Encryption, a fundamental component of IT security, employs cryptographic techniques to obscure sensitive information, ensuring that only authorized users with the appropriate encryption key can access and decipher the encrypted data. By integrating encryption alongside other security protocols, organizations can fortify their defenses and mitigate the risks associated with cybersecurity threats.

Types Of Information Technology Security
Organizations use many types of security tools to protect their data, information, and assets. The most common IT Tools you will find include:
- Application Security protects computer systems, software, and applications from unauthorized access, use, disclosure, disruption, modification, or destruction.
- Cloud Security is the strategy and solutions that protect the cloud infrastructure, and any service or application hosted within the cloud environment, from cyber threats.
- Computer Forensics is a branch of IT security that investigates cyber-attacks by collecting evidence of the crime to be presented in a court of law.
- Endpoint Security protects desktops, laptops, and mobile devices from compromise using technologies like anti-malware solutions, secure web getaways, and endpoint management systems.
- Firewall Security detects and blocks out unsolicited access.
- IoT Security focuses on protecting, monitoring, and remediating threats related to the Internet of Things and the network of connected IoT devices.
- Malware Analyst analyzes malicious software to find out how it works and what it is designed to do.
- Network Security protects networks and programs, including an organization’s IT infrastructure and any network-accessible resources.
- Operational Security is a process to prevent sensitive information from falling into the wrong hands. It identifies actions that may seem innocent but could inadvertently result in critical or sensitive data being revealed or leaked.
Cybercrime incidents are on the rise worldwide, and it keeps organizations busy trying to combat them. The IT industry needs bright young minds to develop more effective protections from these criminals.
